TM SERIES HOURMETERS
The TM Series hourmeters record the operating time of vehicles or powered equipment.
TM SERIES HOURMETERS是机电式的，有一个石英基时计数器，确保精度（在整个范围内优于±0.02%）。它们可以记录多达99999.9小时（对于TM612/624为9999.9小时），并包括自动循环至零小时功能。TM系列型号具有防震、防篡改、完全密封的工程塑料外壳。这些小巧轻便的计时器坚固耐用。它们是对需要低直流电源和可靠计时器的应用的答案。TM612/624型号包括一个三孔安装防震环，用于极端防震。这些计时器可用于任何需要记录工作时间的发动机。它只需要一个直流电源（参考规范）。They are electromechanical and have a quartz base time counter that ensures accuracy (better than ±0.02% over the entire range). They can record up to 99,999.9 hours (9,999.9 for TM612/624) and include an automatic recycle to zero hours feature. The TM Series models have a shock-proof and tamper-proof, totally sealed case made of an engineered plastic. These small, lightweight time meters are rugged and durable. They are the answer to applications requiring a low DC power and reliable hourmeter. The TM612/624 model includes a three-hole mounting shock ring for extreme shock protection. These hourmeters can be used on any engine where operating time needs to be recorded. All it requires is a DC power source (refer to Specifications).
